The 5.0SMDJ12A is a Transient Voltage Suppressor Diode designed for surge and ESD protection in portable communications, computing, and video equipment. This unidirectional device features a working peak reverse voltage (VRWM) of 12V with a breakdown voltage range of 13.4V to 14.7V, and delivers a peak pulse power dissipation of 5000 watts at a 1 ms pulse width. The device is housed in a compact SMC/DO-214AB surface mount package with RoHS compliance and halogen-free construction, offering fast response times of less than 1.0 ps from 0V to breakdown voltage. Key electrical characteristics include a peak forward surge current of 300 amps (8.3 ms single half sine wave), steady-state power dissipation of 6.5 watts at 50°C lead temperature, and a maximum instantaneous forward voltage of 5 volts at 100A peak pulse current. Operating over a temperature range of -55°C to +150°C, the 5.0SMDJ12A is ideal for high-density circuit protection applications requiring reliable transient suppression in compact form factors.
